Open the Case To open: Use a cross screwdriver to loosen the screws and then lift the top case gently. To close: Align the top case with the bottom case and then tighten the screws. 5.2. Installing a SIM Card Open the case and ensure the unit is powered off (unplug the 18-pin cable and switch the internal battery to the OFF position). Insert the SIM card into the holder. Take care to align the cut mark and ensure the SIM card is pushed into the SIM holder completely. Close the case. Figure 5. SIM Card Installation QSZTRACGV620MGUM0100 6 Queclink Confidential GV620MG User Manual 5.3. Installing the Internal Backup Battery GV620MG has an internal backup Li-ion battery (5800mAh, standby time: 120 days without reporting). Figure 6. Backup Battery Installation 5.4. Power Supply Connection PWR (pin 1 or pin 2)/GND (pin 3 or pin 4) are the power input pins. The input voltage range is from 8V to 32V. The device is designed to be installed in vehicles that operate on 12V or 24V systems without the need of external transformers. Figure 7. External Power Supply Connection 5.5. Ignition Detection Table 8. Electrical Characteristics of Ignition Detection Logical Status Active Inactive Electrical Characteristics 5.0V to 32V 0V to 3V or open loop QSZTRACGV620MGUM0100 7 Queclink Confidential GV620MG User Manual Figure 8. Typical Ignition Detection IGN (pin 5) is used for ignition detection. It is recommended to connect this pin to the RUN position of the vehicle ignition switch as shown above. An alternative to connect to the ignition switch is to find a non-permanent power source that is only available when the vehicle is running, for example, the power source for the FM radio. IGN signal can be configured to transmit information to the backend server when ignition is on and enter the power saving mode when ignition is off. QSZTRACGV620MGUM0100 8 Queclink Confidential GV620MG User Manual 5.6. Digital Inputs There are four general purpose digital inputs on GV620MG. They all are negative triggers. Table 9. Electrical Characteristics of the Digital Inputs Logical Status Active Inactive Electrical Characteristics 0V to 0.8V Open loop The following picture shows the recommended connection of a digital input. Figure 9. Typical Digital Input Connection 5.7. Analog Input There is one analogue input on GV620MG, and the analog input voltage range is from 0 to 32V. The following picture shows the recommended connection. Figure 10. Typical Analogue Input Connection Note:
Pin 6 is a multifunction pin: it can be configured as an analogue input. QSZTRACGV620MGUM0100 9 Queclink Confidential GV620MG User Manual 5.8. Digital Outputs There are four digital outputs on GV620MG. All are of open drain type and the maximum drain current is 150 mA. Each output has a built-in over current PTC resettable fuse. Figure 11.

Pay attention to the polarity of the relay if it is pre-installed with an internal flyback diode during connection. Install an additional diode externally if there is no pre-installed internal diode. A common diode such as a 1N4004 one will work in most circumstances. QSZTRACGV620MGUM0100 11 Queclink Confidential GV620MG User Manual 5.9.

TXD and RXD are standard TTL signal. Figure 17. Typical Connection with USB to TTL Serial Port QSZTRACGV620MGUM0100 14 Queclink Confidential GV620MG User Manual 6. Installation Precautions Firmly install the device to a reliable surface to prevent falling off. Make the side with antenna face sky to have better signal reception. Do not install the device under metal surface or in enclosed environments having difficulty in getting GPS and network signal. Install the device in places away from rain water or water may be ponded, otherwise water may seep into the connector to damage the device. Installation Direction: Keep the connector downside if the device is installed vertically, otherwise water (dust) will be held up in the connector to damage the device. Use an electric screwdriver (torque 4.0kg0.2kg) to tighten the screws. Please make sure the tightening torque for every screw is enough and even. Otherwise, the waterproof capability of the device will be deteriorated and water may seep inside causing damage. And such failure will not be covered by the warranty. QSZTRACGV620MGUM0100 15 Queclink Confidential GV620MG User Manual 7. Troubleshooting and Safety Info 7.1. Troubleshooting Table 11. GV620MG Troubleshooting List Problem Possible Reason Solution After the device is turned on, the CEL LED always flashes quickly. The signal is too weak. The device isnt registered to the network. Messages cant be reported to the backend server by network. APN is not right. The IP address or port of the backend server is wrong. Move the device to a place with good network coverage. Ask the network operator for the right APN. Make sure the IP address for the backend server is an identified address in the internet. There is no response from UART when the device is configured by using UART. The port is not ready or the device is not powered on. Please check the port and the device to ensure they are working properly. The device cant get GPS fix. The GPS signal is weak. Move the device to a place under open sky. It is better to make the side with antenna face the sky. 7.2. Safety Info Do not disassemble the device by yourself. Do not put the device in the overheated or too humid place, and avoid exposure to direct sunlight. Too high temperature will damage the device or even cause battery explosion. Do not use the device on the airplane or near medical equipment. QSZTRACGV620MGUM0100 16 Queclink Confidential GV620MG User Manual 8.
